S235 J0 Spiral Steel Pipe - Waxqabadka Wacan ee Dhuumaha Dhexroorka Weyn
Waxaan ku hanweynahay inaan soo bandhigno wax soo saarkayaga ugu sarreeya,S235 J0 Spiral Steel Pipe, looguna talagalay in lagu daboolo baahiyaha sii kordhaya ee warshadaha kala duwan.Sida soo saaraha hormuudka ah ee goobta, waxaan isticmaalnaa tignoolajiyada horumarsan iyo khibrad si aan u soo saarno tayo sare lehDhuumaha khadka oo leh adkeysi gaar ah iyo waxqabad.
Tuubooyinkayada birta wareega ah waxa laga sameeyaa gariiradda birta fidsan iyada oo loo marayo habka alxanka arc laba-geesoodka ah ee iswada leh.Iyada oo loo marayo tiknoolajiyada qaabaynta heerkulka joogtada ah, waxaan hubineynaa in tuubo kasta lagu soo saaro saxnaanta ugu sareysa iyo joogtaynta.Habkan wax-soo-saarka ee taxaddarka leh wuxuu hubinayaa in alaabadayadu ay la kulmaan heerarka tayada ugu sarreeya, taasoo ka dhigaysa inay ku habboon yihiin codsiyo kala duwan.

Tuubooyinkayada birta wareega ah waxa laga sameeyaa gariiradda birta fidsan iyada oo loo marayo habka alxanka arc laba-geesoodka ah ee iswada leh.Iyada oo loo marayo tiknoolajiyada qaabaynta heerkulka joogtada ah, waxaan hubineynaa in tuubo kasta lagu soo saaro saxnaanta ugu sareysa iyo joogtaynta.Habkan wax-soo-saarka ee taxaddarka leh wuxuu hubinayaa in alaabadayadu ay la kulmaan heerarka tayada ugu sarreeya, taasoo ka dhigaysa inay ku habboon yihiin codsiyo kala duwan.
Marka la barbar dhigo tuubooyinka alxanka dhaqameed,S235 J0 tuubooyin bir ah oo wareeg ah waxay leedahay sifooyinka muhiimka ah ee soo socda:
A. Inta lagu jiro habka samaynta, saxanadda birta ah si siman ayay isu beddeshaa waxayna leedahay culayska haraaga ah ee ugu yar.Ma aha oo kaliya in tani ay kordhiso nolosha tuubada, waxay sidoo kale hubisaa in dusha sare ee tuubada ay siman tahay oo aan lahayn xoqin ama cillado.
b.Nidaamkeena alxanka laba-geesoodka ah ee sare u kacay ayaa awood u siinaya alxanka saxda ah ee booska ugu fiican.Tani waxay si weyn u yaraynaysaa dhacdooyinka cilladaha sida cidhifyada aan fiicnayn, alxanka leexashada, iyo alxanka aan dhamaystirnayn.Natiijo ahaan, tuubooyinkayadu waxay leeyihiin tayada alxanka oo aad u fiican, way fududahay in la xakameeyo oo la hubiyo waxqabadka wanaagsan.
C. Tayada ayaa ah mudnaantayada ugu sareysa.Sidaa darteed, waxaanu ku samaynaa 100% kormeer tayo leh oo ku saabsan tuubo kasta oo bir ah oo aan soo saarno.Kormeerkan dhamaystiran wuxuu dammaanad qaadayaa in tubooyinkayadu ay buuxiyaan heerarka ugu sarreeya ee warshadaha, taasoo ku siinaysa nabadda maskaxda inta lagu jiro habka wax soo saarka iyo isticmaalka.
At Cangzhou Spiral Steel Pipe Group Co., Ltd., aad ayaan ugu hanweynahay wax soo saarkaS235 J0 Spiral Steel Pipe.Waxaan ku yaalaa in Cangzhou City, Gobolka Hebei oo u adeegaya warshadaha tan iyo 1993. Daboolaya aag of 350,000 mitir oo laba jibbaaran iyo hantida guud ee 680 million yuan, waxa uu dhigay aasaas adag ee awoodaha wax soo saarka aad u fiican.Kooxdayada gaarka ah oo ka kooban 680 shaqaale xirfad leh ayaa si hagar la'aan ah u shaqeeya si ay u hubiyaan wax soo saarka aan kala go 'lahayn iyo gaarsiinta waqtiga ee 400,000 tan oo tuubooyinka birta ah ee wareega ah sanadkii.

a.Habka deoxidation waxaa loo qoondeeyey sida soo socota: FF: Bir si buuxda loo dilay oo ay ku jiraan curiyayaasha isku xidha nitrogen ee xaddi ku filan in lagu xidho nitrogen la heli karo (tusaale min. 0,020 % wadarta Al ama 0,015 % Al milmaya). b.Qiimaha ugu sarreeya ee nitrogen ma khuseeyo haddii ka kooban yahay kiimikaad uu muujiyo wadarta guud ee Al content ee 0,020 % leh ugu yaraan Al/N saamiga 2:1, ama haddii ku filan walxo kale oo N-xidhitaan ah ay joogaan.Qodobbada N-ku-xidhan waa in lagu diiwaangeliyaa Dukumeentiga Kormeerka. |
